Once in a while I venture out of the Paleozoic to look at younger weird plants... Hermanophyton is a genus based on silicified stems from the Jurassic of the US. It is very likely a gymnosperm but beyond that its affinities are, well, "obscure". #paleobotany #FossilFriday 🌿⛏️ 🧵 1/3
We conducted further morpho-anatomical measurements on leaves and branches in the well-equipped Plant Anatomy Lab at Mahidol Wittayanusorn School 🔬
We sampled canopy branches of dominant tree species in the Mo Singto ForestGEO plot in Khao Yai National Park and measured traits related to tree water losses, including leaf and bark residual conductance thanks to a custom built "Thai-Box".
What a beautiful place to work with an amazing team🌿

« Mitigating climate change requires ending the burning of fossil fuels. Offsets distract from this crucial task. »
La recherche prend de la hauteur avec l'installation d'une passerelle dans la canopée de la forêt expérimentale de @univbordeaux.bsky.social 🌳
Cet aménagement facilitera l'accès aux branches, permettant de compléter les suivis au sol pour étudier la réponse des arbres au changement climatique. 🍃
Nearing the end of an enriching collaboration in Thailand to better understand the physiological mechanisms related to tree mortality within the LEAKY project 🌡️💦
Thanks to PEPR-FORESTT, the warm welcome from the National Biobank of Thailand and support from IRD-AMAP and Univ of Bordeaux 🌳🧪
Freshly published paper led by @santiagotrueba.bsky.social on leaf water losses across vascular plants 🌳🔬🧪
The 50-fold variation in gmin across ecological groups was weakly related to phylogeny with evidence for convergent evolution in response to climate 🌡️💦

We finally organised a short "Thai box" training for colleagues and undergraduate students who inherited this equipment at Chulalongkorn University. Future student projects to come🎓
I am very grateful for all these interactions 🥲

🌳We found a weak trade-off: drought resistant trees tend to be less frost-hardy & vice versa 🌡️🔥❄️
🌲💪 Conifers are generally tougher than angiosperms🌺
🧐No "costs" related to fast-slow economics spectrum 🍃🌱

There is a reason "offsetting" does not exist in the vast majority of cases of avoidable harm to human safety: it would be laughed off as physically absurd and outright fraudulent.
Somehow, in the single most catastrophic physical threat facing our species, it became accepted as normal
Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (g...
Drought and frost stresses play important roles in determining species distributions, especially at range margins. Understanding how stress resistance traits interact to determine vulnerability to c...
